Replace HTMLCollection postAttach's with indexed/named getter

Browse Source 
This solves two issues. First, it's more correct, the indexers should be live.
Second, it makes sure that anything with an HTMLCollection prototype, like
HTMLOptionsCollection, also gets access to the index getters.

We could solve the 2nd issue by making `postAttach` work up the prototype
chain, but since postAttach is wrong (not live), I prefer this solution.
